Nationwide, home prices hit an all-time high for August, rising 8 percent on an annual basis to $250,000. According to Realtor.com Chief Economist Jonathan Smoke, the company’s website traffic also rose to a record high in August, although overall buying activity is tapering off, a typical seasonal pattern that creates a window for buyers who have been unable to seal a deal in what has been a very busy summer.

“With the school year starting now in most of the country, we’re seeing some drop-off in immediate buying interest,” Smoke said. “The current conditions provide more opportunity for any frustrated buyers still in the market to face less competition as we close out the summer.”

For the fourth consecutive month, the Vallejo-Fairfield metro area sits atop Realtor.com’s list of the most-in demand real estate markets, having dethroned San Francisco in the spring. Solano County is by far the Bay Area’s most affordable enclave, with a median single-family home sales price of $381,000 in July, according to a report from the California Association of Realtors.

San Francisco retained its previous month’s spot on August’s list, holding down the No. 4 position. CAR’s data puts the median San Francisco single-family home price at $1,362,500 in July, making it the Golden State’s most expensive real estate market. Along with San Mateo County, San Francisco has California’s largest housing inventory constraints, with a 2.1-months’ supply in July.
